9.2 Differentiating exponentials and logarithms

Question 6

An environmental study models the concentration of a pollutant, $P$ , in a stream as $\ln(0.8t)$ , where $t > 0$ is the time in hours after a treatment process begins. Determine the exact value of the rate of change of the concentration with respect to time at the instant when $t = 2.5$ .
